A browser tool to read winmail.dat TNEF and EML email files privately without uploading.
Mail File Viewer is a private browser tool for reading email files. It opens winmail.dat TNEF and EML messages directly in your browser without uploading them to a server. The tool displays who sent the email, when it was sent, and its contents. It shows images embedded in the message from the file itself while blocking external images until you allow them, and lets you download attachments individually or as a ZIP file. MSG, EMLX, and MHT files are not supported.

Measured after Mail File Viewer went live on Zivaro Launch on 29 October 2026.
Day 5 since launch. Next receipt: day 30, 28 Nov 2026. These are measurements, not proof of cause: many things move these numbers. Figures we have not measured are left out.
EML is a complete email message that contains the sender, recipient, subject, message content, pictures, and attachments. Winmail.dat is an Outlook TNEF package that is used when another mail app hides the original message or attachments inside this wrapper.
No. All files and results stay in your browser. The tool runs on your device, and no files are uploaded.
Images embedded in the email message are shown directly from the file. Images from the internet are blocked by default until you give permission for the current message, and no referrer information is sent.
Mail File Viewer supports winmail.dat (TNEF) and EML files. MSG, EMLX, and MHT files are not supported.
